Puppy loves it but the battery is awful
Color: Blue
Our puppy loves playing with this ball, it does what it says and keeps her occupied for the entire 10-15 minutes the battery lasts. I have to charge it several times a day, though the light never flashes red when the battery is low, it just doesn't work anymore. It also makes a beeping sound when she's playing with it that is super annoying, which sucks because the ball itself isn't super noisy even in the hardwood floors. I wouldn't purchase this again, and we'll probably have to toss it out within a week or two, I really don't see this thing lasting very long. Without the movement, it isn't a ball we would let her play with because she is a strong chewer and the material doesn't seem chew proof at all. I'm only giving it 2 stars because she really does love playing with it, but the battery life and beeping sound are atrocious.

Yes!
Size: Medium
Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls
Size: Medium
My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
